Cassidy was born and raised in the Southwest where she attended Grand Canyon University and earned her B.A. in both History and Communications. During her time in college, she traveled to Eastern Europe to assist at a music camp. The following year Cassidy went to the Middle East to teach English at an American academy. The summer before she graduated, she interned at Center for Arizona Policy (CAP) where she learned about Family Research Council, not knowing that her time at CAP would eventually lead her to working in Washington, D.C. Prior to joining Family Research Council, Cassidy was the Middle Eastern Affairs intern at The Heritage Foundation.
In her spare time, she enjoys reading autobiographies and biographies, learning from people's real-life experiences, working out, building honest and genuine relationships, traveling the United States and the world, experimenting with new recipes, and making people laugh.
